Question Manually control Courant number in a transient simulation

skaar1990 is on a distinguished road
I am trying to solve a 2-D cavity problem which is inherently transient.
Is it possible to specify to Fluent while solving the courant number for ranges of iterations as following for example:

iteration_range--------------courant number
1. 1 to 1000-----------------0.5
2. 1000 to 5000---------------5
3. 5000 to 10000-------------- 50

and so on

Any help regarding courant number control would be helpful.
